AI-Powered Social Media Ad Creation with Website Scraping

This n8n workflow automates the process of generating social media ad content by scraping a website and leveraging AI (Google Gemini) to create compelling ad copy. It then allows for manual review and approval via Slack before finalization.

What it does

  1. Triggers on Form Submission: The workflow starts when a new submission is received via an n8n Form Trigger. This form likely collects the target website URL and possibly other ad-related parameters.
  2. Scrapes Website Content: It uses an HTTP Request node to fetch content from the provided website URL.
  3. Prepares Data for AI: An "Edit Fields (Set)" node processes the scraped data, likely extracting relevant text and formatting it for the AI model.
  4. Generates Ad Copy with Google Gemini: The prepared data is fed into the Google Gemini node, which generates creative and engaging social media ad copy based on the website's content.
  5. Routes for Approval: A "Switch" node is used to route the generated ad copy. This implies there might be different paths based on certain conditions (e.g., ad quality, specific keywords, or a simple approval/rejection flow).
  6. Sends for Human Review (Slack): One of the potential paths from the "Switch" node leads to a Slack node, indicating that the generated ad copy is sent to a designated Slack channel for human review and approval.

Prerequisites/Requirements

  • n8n Instance: A running n8n instance to host the workflow.
  • n8n Form Trigger: You will need to set up and configure the n8n Form Trigger to collect input for the workflow (e.g., website URL).
  • Google Gemini API Key: Credentials for Google Gemini to enable AI content generation.
  • Slack Account & API Token: A Slack workspace and an API token configured as an n8n credential to send messages for review.

Setup/Usage

  1. Import the Workflow: Import the provided JSON into your n8n instance.
  2. Configure Credentials:
    • Set up your Google Gemini credentials with your API key.
    • Configure your Slack credentials to connect to your Slack workspace.
  3. Configure n8n Form Trigger:
    • Open the "On form submission" node.
    • Define the fields you want to collect (e.g., websiteUrl for the target website).
    • Save the form and note its URL.
  4. Configure HTTP Request:
    • Ensure the "HTTP Request" node is configured to use the websiteUrl from the previous "On form submission" node to fetch the website content. You might need to adjust the URL or parameters based on how your form is set up.
  5. Configure Edit Fields (Set):
    • Adjust this node to extract and format the specific data points from the scraped website content that you want Google Gemini to use for ad generation.
  6. Configure Google Gemini:
    • Set up the prompt for the "Google Gemini" node to guide the AI in generating social media ad copy based on the input from the "Edit Fields" node. Specify the desired output format and content style.
  7. Configure Switch Node:
    • Define the conditions in the "Switch" node to route the workflow based on your approval process. For example, you might have a "true" path for sending to Slack and a "false" path for direct publishing (if applicable) or further processing.
  8. Configure Slack Node:
    • Specify the Slack channel where you want the ad copy to be sent for review.
    • Customize the message to include the generated ad copy and any relevant information for the reviewer (e.g., the original website URL).
  9. Activate the Workflow: Once all configurations are complete, activate the workflow.
  10. Trigger the Workflow: Submit the n8n form with a website URL to initiate the ad creation process. The generated ad copy will be sent to your specified Slack channel for review.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
